Answer:
Genus species
Explanation:
Scientists use a special naming system for organisms. It is made up of two words.
The first word is the genus of the organism and the second word is the species of the organism.
The first word, which is the genus, is always capitalized, but the second is not. Both words are italicized if possible, but if you are handwriting the scientific names, an underline suffices.
An example of a scientific name for a house cat is:
Felis catus
In fruit flies, the gene for eye color is located on the X chromosome, and the red eye allele (R) is dominant
to the white eye allele (r). A carrier female is mated with a male fly with genotype X
rY. Which of the
following statements best describes the expected outcome of the cross?
a. The chance of an offspring having red eyes is 75%
b. The chance of an offspring having white eyes is 50%
c. The chance that a male offspring will have white eyes is 0%
d. The chance that a female offspring will have red eyes is 100%
Answer:
b. The chance of an offspring having white eyes is 50%
Explanation:
So the genotype of the male fly is X^r Y. This means the male has white eyes because he only has one X chromosome, so he will express whatever allele is on that chromosome.
The genotype of the female fly, though, is X^R X^r. This is because carriers are heterozygous for traits, and the sex chromosomes of most females is XX (with some exceptions, like XXX, or X (Turner syndrome)).
If we cross this, what are the outcomes? Do a Punnett square. You get the genotypes of X^r X^R, X^r X^r, X^R Y, and X^r Y. The expected phenotypes are a red eye female, white eye female, red eye male, and white eye male.
Now, let's look at the choices:
A.: The chance of an offspring having red eyes is not 75%; it is 50%.
B.: The chance of an offspring having white eyes is 50%!!!
C.: The chance that a male offspring will have white eyes is 50%, not 0%.
D.: The chance that a male offspring will have white eyes is 50%, not 100%.
Sooo, it's B!

Examine the picture of an onion root tip with cells in various stages of the cell cycle. A student claims that interphase is the longest stage of the cell cycle. Another student claims that mitosis is the longest stage. Using evidence from the photo, determine which student is correct and why. A) Mitosis is the longest stage because anaphase requires more time to separate chromatids. B) Interphase is the longest stage because chromosomes are visible in the majority of the cells. C) Mitosis is the longest stage because the majority of the cells in the photo are replicating their DNA. D) Interphase is the longest stage because the majority of the cells in the photo have uncondensed chromatin and are not dividing.
Answer:
B
Explanation:
the longest phase in the cell division is interphase because the DNA replication occurs in this phase
As per the image interphase is the longest stage because the majority of the cells in the photo have uncondensed chromatin and are not dividing. The correct option is D.
What is cell cycle?The cell cycle, also known as the cell-division cycle, is the sequence of events that occurs in a cell that causes it to divide into two daughter cells.
A cell cycle is the series of events that takes place in a cell as it grows as well as divides.
A cell spends the majority of its time in what is known as interphase, where it grows, replicates its chromosomes, and prepares for cell division. The cell then exits interphase, goes through mitosis, and divides completely.
Interphase is the longest stage, according to the image, since the maximum of the cells in the photo have uncondensed chromatin as well as are not dividing.
Thus, the correct option is D.

In the lab simulation, which color peppered moth was able to have the highest rate of survival on the dark bark?
During the Industrial Revolution, explain what caused the population of light-colored peppered moths to decrease and the population of dark-colored peppered moths to increase over time. Be sure to include how the ability to survive and reproduce impacts the process of natural selection.
Predict which color peppered moth would have a better chance of survival in your neighborhood? Explain why.
Answer:
conclusion
Explanation:
hope this helps
Answer:
1. What caused the tree bark to become darker than it was, was the soot from factories in the Industrial Revolution.
2. The light-colored peppered moths have a higher rate of survival on the light bark since it's the same color as it and can't be easily spotted.
3. The dark-colored peppered moths have a higher rate of survival on the dark bark since it's the same color as it and can't be easily spotted.
4. What caused the population of light-colored peppered moths to decrease was the color of the tree bark. The tree bark was dark from the soot from factories. If the tree bark was a dark color, then light-colored peppered moths are more easily spotted, and since the tree bark is a dark color the dark-colored peppered moths can hide more easily, and not be as spotted than the light-colored peppered moths.
5. You have to answer this question. If the tree bark is a dark color, then the dark-colored moths have a better chance of surviving, but if the tree bark is a light color, then the light-colored moths have a better chance of surviving.

Before mitosis begins, which happens before the nucleus starts dividing?
The DNA replicates.
The cytoplasm separates.
The sister chromatids separate.
The homologous chromosomes cross over.
Answer:
The DNA replicates.
Before mitosis begins, the DNA replicates. During the S phase of interphase, which precedes mitosis, the DNA in the nucleus undergoes replication, resulting in the formation of identical sister chromatids.
This ensures that each daughter cell produced during mitosis receives a complete set of genetic information.
After DNA replication, the cell enters the mitotic phase, during which the nucleus divides and the replicated DNA is distributed to the daughter cells.
The cytoplasm separates during cytokinesis, which occurs after mitosis and is not directly related to events before nucleus division. The separation of sister chromatids occurs during anaphase of mitosis, not before the nucleus starts dividing.
Thus, the process of homologous chromosomes crossing over occurs during meiosis, not mitosis.

What might happen to the Burmese python population over time as it reaches or
surpasses its carrying capacity in South Florida? How might other organisms in the
ecosystem be affected? What might happen to the population sizes of various types
of organisms in the Everglades?
Answer:
If the Burmese Python surpasses its carrying capacity, the other organisms might not have enough food, or there is barely a chance of survival for the pythons' prey. The population sizes of other organisms might go down, and go to..extinction :/.
Explanation:
If the Burmese Python exceeds its carrying capacity, other creatures may starve or the pythons' prey may not survive. Other creatures' populations may go extinct.
What is carrying capacity?The typical number of individuals belonging to a species that are found in a given ecosystem is one definition of carrying capacity. The population size of the species is restricted by environmental conditions such as the availability of sufficient food, shelter, water, and mates. In the event that these requirements are not fulfilled, the population will continue to decline until the resource levels recover.
Therefore, if the Burmese Python population grows above its carrying capacity, the other creatures in the area may not have access to enough food, and the prey of the pythons will have an extremely low chance of surviving. It is possible that the population sizes of other organisms will decrease, leading to their eventual extinction.

a) Embryo develops into the fetus
b) Zygote cell rapidly divides

d) Zygote travels down the fallopian tube toward the uterus
Storing hormones, smooth and cardiac muscles are the correct answers.
Storing hormones is not function of skeleton system. Skeleton system protects internal organs such as heart, kidney and lungs etc. It is also responsible for the movement of the muscles as well as produces blood cells because of the presence of bone marrow.
Smooth and cardiac muscles can contract without nervous system stimulation because they are involuntary Muscle which is beyond the control of the nervous system so we can conclude that storing hormones, smooth and cardiac muscles are the correct answers.
